Automatic transfer switches are used to automatically transfer the
main source to standby genarators on failure of the main source/supply.
Upon the main supply is restored, the system automatically change back
and stops the generator,after the short period of cooling down the standby
generator set it will be eventually shut down.
ATS panel can be contactor or breaker type from 100A to 4000A 3 or 4 pole
depends on the requirements, assembled either on Prisma plus P Type tested
enclosure ,Local enclosure or in universal enclosure.Provided by electrical and
mechanical interlocking device and other special components to be:
i. operated both automatically and manually.
ii. Employ to avoid current and voltage surges of instilled breaker
time delay.
iii. Employ automated sensing for over,under voltage, phase sequence
and phase failure.
iv . Installed with generator start/stop commands to indicate incoming
voltage,engine running or faulty conditions ,MCCB/ACB On/Trip
conditions.
*** Engine tests run position for routine test of engine
**** Status signals for remote indications.
